900 MHz Radio trouble..

Hi, good morning team; In my recent purchase from VEX I got a couple of 900 MHz radios to pair my controller to the robot brain. Im having troubles with one of the radios. Im following the instructions to pair the devices and the controller and the Brain are working with the tether cable in the Driver control program. However, with one of the radios I can’t get any radio signal or radio data % reading in the System Info option in the brain. The other radio shows about 60% radio signal and 100% radio data. Can you give me any suggestion to follow up?? Thanks for your time;

I had a problem because one of the radio modules was not completely inserted. Pull it out and push it back in, just to make sure. It should click in place.
